AUGUST 24TH (SATURDAY) 21:17
[SAKURAI]
According to our forensics lab,
there was a luminol reaction
on the skeleton's teeth.
The wound on the victim's leg
was also a match.
However improbable,
it's safe to conclude
that the T-Rex skull
was the tool used
to cause the dismemberment.
See, I told you
I was the Lizard King.
[YU] Can you not point
your spoon at me?
Now that we've confirmed
what caused the injury,
can you explain how you
came to your conclusion?
From the phenomenon itself
and my own observations.
♪
[TAKAO] Based on the bite mark,
an incredibly large creature
must have been responsible
for the injury.
However, there aren't
many animals alive today
that would
fit that description.
We're too far away
from the ocean,
so it couldn't have been
a shark or other sea creature.
Basically, he had
to have been attacked on land
by some behemoth
that went extinct long ago.
Sounds crazy, right?
But then, I noticed
this museum was located nearby
and made the connection.
What a truly
brilliant deduction,
Dr. Ameku, as expected.
No, I don't see
how it makes any sense.
Are you saying the skeleton
moved on its own
-and bit off the victim's leg?
-I wish!
Now that would
be really exciting!
[groans]
If you don't mind, let's put
a pin in that for now.
Could you tell us why exactly
your patient's blood was blue--
[TAKAO]
Hold it.
I handed over info,
so now it's your time to share.
Ah, yes, I do apologize.
How could I forget?
'Cause you're a sneaky tanuki,
that's why.
[TAKAO] First, tell me more
about that skeleton.
Specifically, whether it was
fully built on Friday or not.
[SAKURAI] It was just about
to be fully assembled,
but they had to pause because
of the rain in the afternoon.
[rain splattering]
By the evening, though,
they had finished it.
[TAKAO]
I see.
Next, tell me about the victim.
Have you ID'd him yet?
[SAKURAI]
Yes, Kousuke Kumade, 23.
He served time
in prison for assault.
[scoffs]
[SAKURAI] When he got out,
he was seen entering
the HQ of a known gang.
So, a hoodlum, in other words.
[TAKAO]
How was the body found?
[SAKURAI]
Jiro Manabe discovered it.
He's the construction
site supervisor,
a man in his 50s.
Work halted due to the rain,
but he got worried
and went to inspect the site.
[Manabe gasps]
[SAKURAI]
And there was Kumade.
So, I imagine this Manabe
called emergency services?
[SAKURAI]
Actually, no.
The doctor at a nearby clinic
was the one who made the call.
Sorry?
[SAKURAI] The privately owned
Hachisuka Clinic was nearby.
Manabe rushed straight there.
The director, Dr. Hachisuka,
is considered
a skilled physician,
so Manabe brought him
to examine Kumade.
Why would he do that?
I mean, the victim
had a severed leg.
[YU] There wasn't anything
that could've been
done for him there?
[SAKURAI] That's what
Dr. Hachisuka thought as well.
So, he immediately called
emergency services
and began doing
chest compressions.
[sighs]
♪
Um?
[YU]
What's wrong?
[grunts]
[YU]
Dr. Takao?
[grunts]
What in the
-Ow!

You could've asked me to move!
Wait, where are you
rushing off to?
Duh, Hachisuka Clinic,
where else?
HACHISUKA CLINIC
GASTROENTEROLOGY SURGERY
CLOSED: TUESDAYS AND FRIDAYS
[YU]
I figured.
Dr. Takao
you realize
it's almost 10:00 at night?
Let's come back tomorrow.
[footfall]
Uh, hello?
Um, that's not the way home.
[footfall]
♪
[YU] For the record,
I think this is a bad idea.
[Yu sighs]
[door bell ringing]
Stop being a nuisance!
You're acting like you get
a prize or something
if you can ring it
enough times!
What do you think you're doing?
That's what I asked you!
What is going on?
Yellow tang, blue tang,
bluestreak cleaner wrasse,
carpenter's flasher wrasse.
Huh?
You know your tropical fish?
[TAKAO] You must be
the director, Hachisuka.
I am, yes.
But wait,
who in the world are you?
The Director of Investigative
Pathology at Tenikai General,
Takao Ameku.
Tenikai?
[NARUSE] You two need
to get out of here, now.
Oh, good evening, officers.
[SAKURAI]
I'm very sorry.
We're consulting with her.
You know, about the deceased
man with the missing leg
that was discovered
behind the museum.
I see.
[TAKAO] I was curious
why you didn't treat that man
at your private clinic.
You do have a surgery room.
Because there was
nothing I could do.
[HACHISUKA]
His leg was severed,
and his heart
had already stopped.
We were closed that day, and
there were no nurses on site.
Nothing could have
been done to save him.
Your hospital should know that.
[chuckles]
That's explains that.
[TAKAO]
Let's go, Kotori.
Huh?
So, we're done here?
[TAKAO]
Yeah.
-Oh, and, Sakurai?
-[SAKURAI] Huh?
Have your crime lab take
a look around the museum
first thing tomorrow morning.
[SAKURAI]
The museum?
-[SAKURAI] For clues?
-That's right.
It won't be long now
before the case gets solved.
I'm 100% convinced the culprit
left behind
vital evidence there.
[chuckles]
[Sakurai sighs]
[SAKURAI] Um, Dr. Ameku,
where are you taking us?
[NARUSE] You couldn't have
chosen a more difficult path.
Explain yourself already.
Why should I explain
myself to those
who are so stingy
with information?
-[SAKURAI] Hm?
-And what does that mean?
Behind this case,
there's a much larger one
that you're keeping hidden.
I'm not sure I follow.
Kotori, did you
happen to notice
all the suspicious men
around the crime scene earlier?
What men?
Oh!
[YU] The ones that looked
like they were yakuza?
[TAKAO]
Yeah.
Do you remember
what you said last night?
I'm too busy for this.
The Fourth Precinct's
been making
a real fool of itself lately.
-Well?
-[gasps]
The Fourth Precinct,
called the Organized
Crime Department now.
So, it turns out
they were actually police?
But why were they at the scene?
Try casting your mind back.
There was another
incident here yesterday.
Let me think.
[sighs]
Involving Organized Crime?
♪
Ah!
SHOOTING IN NERIMA WARD
[YU]
The Nerima shooting!
[fingers snapping]
Good work, my pupil.
A dangerous incident
that could've involved
innocent civilians.
[TAKAO]
And the shooter was
Kumade, yes?
After the body
was ID'd last night,
they learned he was the one
they were looking for.
Just one problem.
The person he shot was
a member of the yakuza.
Am I correct?
-You've lost me again.
-[sighs]
The police are convinced
the yakuza are responsible
and took Kumade's life
out of revenge.
That's why HQ set up
the investigation so fast.
If this case
isn't resolved quickly,
it may lead to an all-out war
between two rival gangs.
[SAKURAI]
What can I say, Dr. Ameku?
You do not disappoint.
Again, absolutely right.
[running footsteps]
[gunshots]
[TAKAO] Did the yakuza member
shot by Kumade die?
-Get back here!
-[SAKURAI] No.
[SAKURAI] He's seriously
wounded, but still alive.
The guy's second-in-command
of a minor yakuza gang
that's currently at odds
with the gang Kumade's in.
Kumade fled after
being shot at himself.
The wound must have
slowed him down,
and he ended up getting
caught by the gang,
tortured, and murdered.
[SAKURAI] That's what
we believe right now.
You said he was being shot at.
[TAKAO] Meaning a bullet
might have hit him
and left bloodstains.
There might have
been some, yes.
-[panting]
-[TAKAO] What color were they?
[SAKURAI]
Red.
You know, like normal blood.
[MALE YAKUZA MEMBER 2B]
Find him!
Red.
That's right, detective.
[TAKAO]
Just like normal blood.
[sighing]
[TAKAO]
Oh, that reminds me.
Weren't you planning
on taking a closer look
around the museum either way?
[Sakurai and Naruse gasping]
For instance, why was the lock
on the back door broken,
perhaps?
How'd you know--
[TAKAO] [scoffs]
As I thought.
So, you already know
how everything played out?
[TAKAO] While I have a theory,
I'm not certain enough
to say it aloud yet.
That's why I'm confirming
my suspicions.
Okay, but where
are you taking us?
[YU]
The museum?
[footfall]
DO NOT ENTER
[door knob clanking]
[switch clicks]
[footfall]
[TAKAO]
And there it is.
There's what?
Wait, is that
what I think it is?
[TAKAO]
Yup.
Blood from our victim.
-What?
-Now hold up just a second!
[SAKURAI] Are you telling us
Kumade was dragged
all the way here?
For what reason?
[TAKAO] That, my detective,
is the biggest clue
to solving this mystery.
Good news.
[TAKAO]
If we follow the blood,
it should lead us
to the answer.

[TAKAO]
That was pretty interesting.

[TAKAO]
First off, let's ask ourselves
why his blood was blue.
Also, how did his leg come
to be bitten off
by the Tyrannosaurus Rex?

For this mystery, allow me
to present my diagnosis.
AMEKU M.D.: DOCTOR DETECTIVE
[Hachisuka panting]
[door creaking open]
[HACHISUKA]
Huh?
[footfall]
[doorknob jiggles]
[sighs]
[groaning]
[sighing]
[gasps]
Well, good evening, Doc.
What a surprise running
into you at this hour.
-[gasps]
-I can't believe
he really came back here.
[SAKURAI]
Now, if you'd be so kind,
would you explain
all of this to us, Dr. Ameku?
-My pleasure.
-[Hachisuka gasps]
Before we declare
this case closed,
we need to carefully consider
every event that transpired
and how they connect.
[TAKAO]
The body with the blue blood.
The leg bitten off
by a Tyrannosaurus Rex.
The Nerima shooting.
The blue stain
in the storage room.
Once you put
the pieces together,
you get a sense
of the bigger picture.
Don't you think,
Director Hachisuka?
[whimpering]
[TAKAO] First and foremost,
we should focus
on the victim's blood,
and why it was that color.
The phenomenon itself
isn't that strange.
-Kotori?
-[YU] Yes?
If a patient's blood is blue,
what's the first condition
that springs to mind?
Hmm.
Well, let me think.
A disease like that
would most likely be
[gasps]
Methemoglobinemia.
Very good.
Could you explain
what that is to a layman?
[YU] It's a disorder
where the hemoglobin
in red blood cells gets
oxidized and turns blue,
hindering the normal
transport of oxygen.
Symptoms are dyspnea
and also impaired
consciousness.
It can lead to death
in extreme cases.
You're saying Kumade had
gotten this disorder somehow?
[TAKAO] To be precise,
in the short time between
when Kumade got shot
and when he died,
something else happened.
That something caused
the disorder to develop.
[NARUSE]
"Something" as in what?
[TAKAO] After executing
the rival gang's number two,
he was hit
by return fire and fled.
There's pretty much only
one thing to do after that.
Seek out a doctor?
[TAKAO]
Precisely.
Methemoglobinemia
usually shows up as a symptom
after being poisoned
by something.
But it can occasionally
be caused by drugs
like procaine and lidocaine.
And those are what now?
[YU]
Local anesthetics.
Kumade must have shown
signs of methemoglobinemia
after he received them
and died from lack of oxygen.
-[YU] Am I right?
-You are.
[SAKURAI] But Kumade
didn't just suddenly die
in a hospital.
This wouldn't even be a case
if he'd gone
to a proper hospital.
-[Hachisuka whimpering]
-[SAKURAI] What do you mean?
[TAKAO] Kumade didn't
have a normal injury.
He had gotten shot
during a gunfight.
[gasps]
The bullet was still
in his body.
I get it.
He risked being found out
if he went
to an actual hospital.
His one choice was to seek help
from a corrupt
medical institution.
[SAKURAI]
A doctor for the underworld.
That's right,
a certain Hachisuka Clinic.
Turns out his clientele
includes organized crime.
[whimpering]
[TAKAO]
During the procedure,
a large amount
of local anesthesia
must have been used on Kumade.
As a result, he exhibited
methemoglobinemia,
and his condition
immediately became dire.
Fearing others would
discover his unsavory ties,
Hachisuka didn't take Kumade
to a fully equipped hospital.
Instead, he came here.
The one place
he could continue treatment.
[SAKURAI] That's the part
I'm still not clear on.
Why sneak a dying man
in here, of all places?
Because it had
the proper drugs.
[SAKURAI]
What drugs?
[TAKAO] Kotori,
would you kindly explain
how methemoglobinemia
is treated?
Huh?
Well, uh, you would need
oxygen therapy, right?
Come on, we both know
all that would do
is take care of the symptoms.
[TAKAO] In order
to properly treat him,
you'd need medicine
that turns methemoglobin
back into hemoglobin.
-[YU] Which is? Gimme a sec.
-[TAKAO] Good grief.
[TAKAO] You should
know this as a doctor
of internal medicine.
[whimpering]
[NARUSE] [gasps]
Is that Kumade's blood?
[TAKAO] Nope, this is what
would have saved him.
-[TAKAO] Methylene Blue.
-[NARUSE] What is it?
[TAKAO]
An aqueous solution
with a chemical
reducing effect.
It can be appropriately used
to treat methemoglobinemia
and administered orally
or intravenously.
[SAKURAI]
Just a second.
Why would the museum have
something like this on hand?
It's quite simple.
[TAKAO] Methylene blue
is used to kill pathogens
that cause white spot disease
and water mold on fish.
[SAKURAI]
Fish?
Turns out you knew
a lot of breeds, too.
[groaning]
Yellow tang, blue tang,
bluestreak cleaner wrasse,
carpenter's flasher wrasse.
Huh?
You know your tropical fish?
[TAKAO]
Based on the number of fish
the museum took care of,
you realized they must
have methylene blue.
GRAND AQUARIUM OF TROPICAL FISH
Kumade needed treatment
as soon as possible.
EQUIPMENT STORAGE
That's why you had to drag him
to the storage room.
♪
And the large blue stain
we found on the floor inside.
[TAKAO]
This man tried to treat Kumade
by making him drink
methylene blue.
-[TAKAO] One problem.
-[gasps]
[TAKAO] He was already
dead by then, wasn't he?
[groans]
-[TAKAO] You panicked
and accidentally -Hey!
-knocked over the container.
-[HACHISUKA] Hey!
[TAKAO]
That's the reason we found it
in the storage room.
[SAKURAI] But, can we
get back to how his leg got
bitten off by the T-Rex?
You have to put yourself
in this guy's shoes.
If the body had been left
the way it was,
it would've been obvious
he had received medical help.
[SAKURAI]
That's true.
He severed the leg.
[TAKAO] After all, the bullet
wound would have been evidence.
[YU] So that was the location
of the gunshot wound.
Removing a human leg
isn't the easiest thing
in the world,
even for a doctor.
How very astute!
[TAKAO] And of course,
he couldn't use proper tools
to do it, either.
He wanted to make it impossible
for someone to tell
he had tried treating the leg.
He could only sever
the limb forcefully
with some kind
of heavy bladed object.
That's when he chanced upon it.
♪
A head lined
with enormous fangs.
The perfect
instrument for the job.
The ideal sharpened tool,
68 million years
in the making.
[Hachisuka grunts]
[TAKAO] Afterward,
he carried the corpse
through the forest
behind the museum
and dumped it at the empty
construction site.
[sighs]
[TAKAO]
Ohyou didn't expect
that someone would find
the body right away, did you?
But, wait
Using the coincidence
to your advantage
you gave chest compressions
to Kumade,
who was already dead by then.
Then called emergency services.
That is smart.
They wouldn't be declared dead
if a doctor was the one
administering compressions.
[SAKURAI] By pretending to do
life-saving measures,
he delayed police involvement.
[TAKAO] And the rain
took care of the evidence
during the wait.
So, there you
have it, case closed.
The truth has been revealed.
I will say, that part about
using the T-Rex skull
and giving chest compressions?
[chuckles]
It was pretty ingenious stuff.
He would've pulled off
the perfect crime.
[whimpering]
Too bad for him,
he didn't count on one thing.
The hospital the victim was
taken to had its own genius.
[growls]
Now then, do you wish
to clarify anything?
Youyou don't
have any proof!
Hey, come on now.
Did you already forget
what I said
when I was at your clinic?
Oh, and, Sakurai?
Have your crime lab
take a look around the museum
first thing tomorrow morning.
[SAKURAI] The museum?
For clues?
Surely not.
Oh, I surely did.
[TAKAO] You panicked
and came back here.
For the methylene blue.
After all, your fingerprints
are all over the bottle.
Not a sophisticated trap,
but you fell for it.
[HACHISUKA] I So what if
my fingerprints are on it?
You can't prove
I cut off that guy's leg
and abandoned the body.
That's not enough to arrest me!
[TAKAO]
Ah, you really don't get it.
[gasps]
You think you're getting
arrested for damaging
and abandoning a cadaver?
[HACHISUKA]
Huh?
[TAKAO] You're going to be
arrested for breaking
and entering into the museum
with the intent to steal.
[Hachisuka gasps]
[TAKAO] Of course,
your clinic will be searched
after your arrest.
Who knows?
We might even end up recovering
some evidence there, too,
including Kumade's
fingerprints and blood.
Hey, we might even find
a leg in need of a body.
[gasps]
[sighing]
My diagnosis is complete.
Come along quietly.
[SAKURAI] Thank you for all
your assistance, Dr. Ameku.

The rest is up to you guys.

behind the museum.
I see.
[TAKAO] I was curious
why you didn't treat that man

You do have a surgery room.
Because there was
nothing I could do.
[HACHISUKA]
His leg was severed,
and his heart
had already stopped.
We were closed that day, and
there were no nurses on site.
Nothing could have
been done to save him.

SHOOTING IN NERIMA WARD

The Nerima shooting!
[fingers snapping]
Good work, my pupil.
A dangerous incident
that could've involved
innocent civilians.
[TAKAO]
And the shooter was
Kumade, yes?
After the body
was ID'd last night,
they learned he was the one
they were looking for.
Just one problem.
The person he shot was
a member of the yakuza.
Am I correct?
-You've lost me again.
-[sighs]
The police are convinced
the yakuza are responsible
and took Kumade's life
out of revenge.
That's why HQ set up
the investigation so fast.
If this case
isn't resolved quickly,
it may lead to an all-out war
between two rival gangs.
[SAKURAI]
What can I say, Dr. Ameku?
You do not disappoint.
Again, absolutely right.

[TAKAO] Did the yakuza member
shot by Kumade die?

wounded, but still alive.
The guy's second-in-command
of a minor yakuza gang
that's currently at odds
with the gang Kumade's in.
Kumade fled after
being shot at himself.
The wound must have
slowed him down,
and he ended up getting
caught by the gang,
tortured, and murdered.
[SAKURAI] That's what
we believe right now.
You said he was being shot at.
[TAKAO] Meaning a bullet
might have hit him

There might have
been some, yes.

Huh?

[groaning]

Well, good evening, Doc.
What a surprise running
into you at this hour.

[SAKURAI]
Now, if you'd be so kind,
would you explain
all of this to us, Dr. Ameku?
-My pleasure.
-[Hachisuka gasps]
Before we declare
this case closed,
we need to carefully consider
every event that transpired
and how they connect.
[TAKAO]
The body with the blue blood.
The leg bitten off
by a Tyrannosaurus Rex.
The Nerima shooting.
The blue stain
in the storage room.
Once you put
the pieces together,
you get a sense
of the bigger picture.
Don't you think,
Director Hachisuka?
[whimpering]
[TAKAO] First and foremost,
we should focus
on the victim's blood,
and why it was that color.
The phenomenon itself
isn't that strange.
-Kotori?
-[YU] Yes?
If a patient's blood is blue,
what's the first condition
that springs to mind?
Hmm.
Well, let me think.
A disease like that
would most likely be
[gasps]
Methemoglobinemia.
Very good.
Could you explain
what that is to a layman?
[YU] It's a disorder
where the hemoglobin
in red blood cells gets
oxidized and turns blue,
hindering the normal
transport of oxygen.
Symptoms are dyspnea
and also impaired
consciousness.
It can lead to death
in extreme cases.
You're saying Kumade had
gotten this disorder somehow?
[TAKAO] To be precise,
in the short time between
when Kumade got shot
and when he died,
something else happened.
That something caused
the disorder to develop.
[NARUSE]
"Something" as in what?
[TAKAO] After executing
the rival gang's number two,
he was hit
by return fire and fled.
There's pretty much only
one thing to do after that.
Seek out a doctor?
[TAKAO]
Precisely.
Methemoglobinemia
usually shows up as a symptom
after being poisoned
by something.
But it can occasionally
be caused by drugs
like procaine and lidocaine.
And those are what now?
[YU]
Local anesthetics.
Kumade must have shown
signs of methemoglobinemia
after he received them
and died from lack of oxygen.
-[YU] Am I right?
-You are.
[SAKURAI] But Kumade
didn't just suddenly die
in a hospital.
This wouldn't even be a case
if he'd gone
to a proper hospital.
-[Hachisuka whimpering]
-[SAKURAI] What do you mean?
[TAKAO] Kumade didn't
have a normal injury.
He had gotten shot
during a gunfight.
[gasps]
The bullet was still
in his body.
I get it.
He risked being found out
if he went
to an actual hospital.
His one choice was to seek help
from a corrupt
medical institution.
[SAKURAI]
A doctor for the underworld.
That's right,
a certain Hachisuka Clinic.
Turns out his clientele
includes organized crime.
[whimpering]
[TAKAO]
During the procedure,
a large amount
of local anesthesia
must have been used on Kumade.
As a result, he exhibited
methemoglobinemia,
and his condition
immediately became dire.
Fearing others would
discover his unsavory ties,
Hachisuka didn't take Kumade
to a fully equipped hospital.
Instead, he came here.
The one place
he could continue treatment.
[SAKURAI] That's the part
I'm still not clear on.
Why sneak a dying man
in here, of all places?
Because it had
the proper drugs.
[SAKURAI]
What drugs?
[TAKAO] Kotori,
would you kindly explain
how methemoglobinemia
is treated?
Huh?
Well, uh, you would need
oxygen therapy, right?
Come on, we both know
all that would do
is take care of the symptoms.
[TAKAO] In order
to properly treat him,
you'd need medicine
that turns methemoglobin
back into hemoglobin.
-[YU] Which is? Gimme a sec.
-[TAKAO] Good grief.
[TAKAO] You should
know this as a doctor
of internal medicine.
[whimpering]
[NARUSE] [gasps]
Is that Kumade's blood?
[TAKAO] Nope, this is what
would have saved him.
-[TAKAO] Methylene Blue.
-[NARUSE] What is it?
[TAKAO]
An aqueous solution
with a chemical
reducing effect.
It can be appropriately used
to treat methemoglobinemia
and administered orally
or intravenously.
[SAKURAI]
Just a second.
Why would the museum have
something like this on hand?
It's quite simple.
[TAKAO] Methylene blue
is used to kill pathogens
that cause white spot disease
and water mold on fish.
[SAKURAI]
Fish?
Turns out you knew
a lot of breeds, too.
[groaning]
Yellow tang, blue tang,
bluestreak cleaner wrasse,
carpenter's flasher wrasse.
Huh?
You know your tropical fish?

Based on the number of fish
the museum took care of,
you realized they must
have methylene blue.

[SAKURAI] But, can we
get back to how his leg got
bitten off by the T-Rex?
You have to put yourself
in this guy's shoes.
If the body had been left
the way it was,
it would've been obvious
he had received medical help.
[SAKURAI]
That's true.
He severed the leg.
[TAKAO] After all, the bullet
wound would have been evidence.
[YU] So that was the location
of the gunshot wound.
Removing a human leg
isn't the easiest thing
in the world,
even for a doctor.
How very astute!
[TAKAO] And of course,
he couldn't use proper tools
to do it, either.
He wanted to make it impossible
for someone to tell
he had tried treating the leg.
He could only sever
the limb forcefully
with some kind
of heavy bladed object.
That's when he chanced upon it.

through the forest
behind the museum

Ohyou didn't expect
that someone would find
the body right away, did you?
But, wait
Using the coincidence
to your advantage
you gave chest compressions
to Kumade,
who was already dead by then.
Then called emergency services.
That is smart.
They wouldn't be declared dead
if a doctor was the one
administering compressions.

life-saving measures,
he delayed police involvement.

have it, case closed.

using the T-Rex skull
